- Background
Recently, there has been increasing worldwide concern about outdoor air pollution, especially particulate matter (PM), which has been extensively researched for its harmful effects on the respiratory system. However, sufficient research on its effects on cardiovascular diseases, such as hypertension, remains lacking. In this study, we examine the associations between PM levels and hypertension and hypothesize that higher PM concentrations are associated with elevated blood pressure. MethodsA total of 133,935 adults aged ≥ 40 years who participated in the Korean Genome and Epidemiology Study were analyzed. Multiple linear regression analyses were conducted to investigate the short- (1–14 days), medium- (1 and 3 months), and long-term (1 and 2 years) impacts of PM on blood pressure. Logistic regression analyses were conducted to evaluate the medium- and long-term effects of PM on blood pressure elevation after adjusting for sex, age, body mass index, health-related lifestyle behaviors, and geographic areas. ResultsUsing multiple linear regression analyses, both crude and adjusted models generated positive estimates, indicating an association with increased blood pressure, with all results being statistically significant, with the exception of PM levels over the long-term period (1 and 2 years) in non-hypertensive participants. In the logistic regression analyses on non-hypertensive participants, moderate PM10 (particulate matter with diameters < 10 μm) and PM2.5 (particulate matter with diameters < 2.5 μm) levels over the long-term period and all high PM10 and PM2.5 levels were statistically significant after adjusting for various covariates. Notably, high PM2.5 levels of the 1 year exhibited the highest odds ratio of 1.23 (95% confidence interval: 1.19–1.28) after adjustment. ConclusionsThese findings suggest that both short- and long-term exposure to PM is associated with blood pressure elevation.
- 대기 중 미세먼지 농도와 고혈압과의 연관성: 한국인유전체역학조사사업 자료를 기반으로
목적 환경보건에서 대기 중 미세먼지 농도의 중요성이 갈수록 커지고 있으나 아직 미세먼지 농도와 고혈압과의 연관성에 대한 연구 결과가 충분하지 못하여 확실한 결론을 내리기 어려운 상황에 처해있다. 본 연구는 대기 중 미세먼지 노출과 혈압 상승의 상관관계를 밝히는 데에 목적을 두고 있다.
방법 본 연구는 질병관리청 국립보건연구원에서 담당하고 있는 한국인유전체역학조사사업 코호트와 대기오염 모니터링 자료가 연계된 데이터에서 추출한 133,935 명을 대상으로 하였다. 다중선형 회귀분석과 로지스틱 회귀분석을 수행하여 대기 중 미세먼지 농도와 혈압 수준과의 상관관계를 평가하였다.
결과 다중선형 회귀분석에서는 성별, 나이 등과 같은 공변수들을 보정하기 전과 후 모두 통계적으로 유의하게 미세먼지 농도가 증가할수록, 혈압이 상승하였다. 로지스틱 회귀분석에서 고혈압의 오즈비(odds ratio; OR)는 높은 대기 중 미세먼지 농도에 노출된 참여자들에서 통계적으로 유의하게 증가한 반면, 중등도의 미세먼지 농도에 노출된 참여자들에서는 노출기간에 따라 결과가 달라지는 양상을 보였다.
결론 본 연구의 결과는 대기 중 미세먼지 노출이 고혈압 위험도 증가와 관련될 수 있음을 시사한다.

- Background
This study aimed to determine the effect of specific working postures on the development of varicose veins (VV). By using Korea's National Health Insurance (NHI) and National Employment Insurance (NEI) data, we analyzed the general characteristic and difference in proportions of VV cases according to occupational working posture. MethodsFrom the NEI and NHI data, participant demographics, such as gender, age, body mass index, and number of workers in specific occupations or industries were obtained. We classified the 240 occupations into blue-collar (BC) and white-collar (WC) occupations and subdivided them into standing, sitting, and walking groups according to the dominant working posture. ResultsThe number of VV patients per 100,000 individuals increased with age, with a higher number of women than men and a higher number of patients in the BC than WC groups. For the BC group, the proportion of VV cases was the highest in the standing group, followed by the walking and sitting groups, but there was no significant difference between standing and walking groups in man. For the WC group, the standing group had a higher proportion of VV cases than the sitting group, but there was no significant difference between the standing and sitting group in man. In the BC group, the proportion of VV cases was the highest among medical and welfare-related elementary workers, bakers and cookie makers, automobile assemblers, cleaning and guarding-related elemental workers, and nurses and dental hygienists. In the WC group, the proportion of VV cases was the highest among food/lodging/tourism/entertainment/sports-related managers, environment/cleaning/protective services-related managers, finance and insurance clerks, accounting book-keeping clerks, and social welfare and counseling professionals. ConclusionsThis study was performed to determine the characteristics of VV with different working posture among Korean workers. It is expected to be the basis of further studies on occupational musculoskeletal diseases.
